OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor (PPI) or potassium-competitive acid blocker (P-CAB) for Helicobacter pylori (Hp) eradication. METHODS Randomized controlled trial (RCTs) on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed, Embase, the Cochrane Library, Web of Science, CNKI, Wanfang, and VIP data. The search time frame was from database inception to September 5, 2025. After literature screening, data extraction, and quality assessment, a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included, encompassing 8 therapeutic regimens: PPI combined with high-dose amoxicillin for 14 days (TR1), PPI combined with low-dose amoxicillin for 14 days (TR2), P-CAB combined with high-dose amoxicillin for 7 days (TR3), P-CAB combined with high-dose amoxicillin for 14 days (TR4), P-CAB combined with high-dose amoxicillin for 10 days (TR5), P-CAB combined with low-dose amoxicillin for 7 days (TR6), P-CAB combined with low-dose amoxicillin for 14 days (TR7), and P-CAB combined with low-dose amoxicillin for 10 days (TR8). The network meta-analysis results showed that, in terms of intention-to-treat Hp eradication rates, the eradication rates of TR5 and TR4 were significantly higher than those of TR3, TR8, TR6 and TR1 ( P <0.05). The surface under the cumulative ranking curve (SUCRA) values from highest to lowest were: TR4 (89.7%)>TR5 (82.3%)>TR7 (71.5%)> TR2 (48.6%)>TR1 (43.9%)>TR8 (28.7%)>TR3 (22.7%)>TR6 (12.6%). Regarding safety, the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 ( P <0.05). The SUCRA values from highest to lowest were: TR1 (91.3%)>TR4 (79.8%)>TR5 (55.0%)>TR7 (50.9%)>TR8 (41.3%)>TR2 (36.4%)>TR3 (27.6%) >TR6 (17.7%). CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy, the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

ObjectiveTo investigate the contamination status of ochratoxin A (OTA) in commercially available food products in Shanghai, and to assess OTA exposure levels and the associated non-carcinogenic and carcinogenic risks among pregnant women by integrating dietary consumption data of this population. MethodsThe levels of OTA contamination in 1 520 food samples collected in Shanghai from 2022 to 2023 were determined using liquid chromatography-tandem mass spectrometry. An exposure assessment model was developed based on the dietary consumption levels of pregnant women from the 2016‒2017 Shanghai Pregnant Women Dietary Monitoring Survey to calculate the estimated daily intake (EDI) of OTA, the margin of exposure for non-carcinogenic toxicity (MOE1), and the margin of exposure for carcinogenic toxicity (MOE2). An MOE1 greater than 200 and an MOE2 greater than 10 000 indicate that the non-carcinogenic toxicity and carcinogenic toxicity resulting from exposure are negligible, respectively. For samples with OTA contamination levels below the limit of detection (LOD), which accounted for more than 80% of the samples, the OTA levels were assigned values of 0 and LOD, respectively, for subsequent calculations. ResultsThe detection rates of OTA in cereals, nuts, dried fruits, and alcohol samples collected in 2022 were 2.03%, 0, 0, and 0, respectively. The OTA detection rates in cereals, nuts, dried fruits, beans, and alcohol samples collected in 2023 were 2.50%, 0.39%, 2.47%, 1.67%, and 13.33%, respectively. For pregnant women in Shanghai in 2022, simulation results indicated that when assigning a value of 0 and the LOD, theP50 values of EDI for dietary OTA exposure were 0.05 and 0.72 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.25 and 2.40 ng·(kg·d)-1, respectively. For pregnant women in Shanghai in 2023, the P50 values of EDI for dietary OTA exposure were 0.04 and 1.00 ng·(kg·d)-1, respectively, and the P95 values of EDI for dietary OTA exposure were 0.23 and 2.67 ng·(kg·d)-1, respectively, both substantially below the tolerable daily intake (TDI) for OTA [17 ng·(kg·d)-1]. The EDI for dietary OTA exposure in 100.0% of Shanghai pregnant women was lower than the TDI, indicating an overall low level of dietary OTA exposure among this population. For 100.0% of pregnant women, the MOE₁ for dietary OTA exposure exceeded 200. When assigned a value of 0, the MOE₂ for 100.0% of pregnant women in both 2022 and 2023 exceeded10 000. When assigned the LOD value, 72.3% and 81.8% of pregnant women in 2022 and 2023, respectively, had an MOE₂ exceeding 10 000. ConclusionFrom 2022 to 2023, samples of cereals, nuts, dried fruits, beans, and alcohol sold in Shanghai exhibited varying degrees of OTA contamination. The overall EDI of OTA exposure among pregnant women in Shanghai remained at a low level. The non-carcinogenic and carcinogenic risks associated with OTA exposure were generally low and at controllable levels.

BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

OBJECTIVE:
To explore the clinical, genetic, therapeutic and prognostic characteristics of two children with Lesch-Nyhan syndrome (LNS) in order to enhance understanding of this disease and formulate more effective therapeutic strategies.
METHODS:
Clinical data were collected from two children clinically diagnosed with LNS who were treated at Anhui Provincial Children's Hospital from April 2023 to January 2024. Data were retrospectively collected and included clinical manifestations (symptoms, signs, laboratory and imaging findings), treatment course, and results of follow-up. Peripheral venous blood samples were obtained from child 1 and his parents. Whole-exome sequencing (WES) was performed. Candidate variants were validated by Sanger sequencing. Standard bioinformatic analysis of the raw WES data was conducted, including quality control, alignment, variant calling, and annotation. Candidate pathogenic variants were filtered using population frequency databases (e.g., gnomAD), disease databases (e.g., OMIM, ClinVar), and multiple in silico pathogenicity prediction tools (e.g., SIFT, PolyPhen-2, CADD). Phenotype matching was integrated using Human Phenotype Ontology (HPO) terms. Pathogenicity classification of variants was performed according to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants (2015). This study was approved by the Medical Ethics Committee of Anhui Children's Hospital, Children's Hospital of Fudan University (Ethics No.: EYLL-2014-027).
RESULTS:
Child 1, a 4-year-old boy, had presented with developmental delay for over 3 years, accompanied by abnormal postures and involuntary lip-biting. Physical examination revealed limb dystonia, anxious expression, lower lip damage, and communication difficulties. Laboratory tests showed hyperuricemia and renal stones. Genetic testing identified a hemizygote variant of the HPRT1 gene, c.135G>T (p.Arg45Ser), inherited from an asymptomatic carrier mother, which confirmed the diagnosis of LNS. This variant was absent from population databases (gnomAD, 1000 Genomes, dbSNP). Protein function prediction tools consistently indicated it as a pathogenic or likely pathogenic variant (SIFT, PolyPhen-2, CADD, and REVEL scores all reached pathogenic thresholds). Protein structural modeling revealed that the variant may disrupt the hydrogen-bonding network compromising the tetramer stability. ACMG classification designated it as likely pathogenic (PM1+PM2_Supporting+PM5+PP3). The patient was treated with benhaxol hydrochloride, baclofen, and clonazepam to improve his neurological symptoms, in addition with treatment with febuxostat from the Nephrology Department to manage his purine metabolism. After one year of follow-up, the patient's abnormal posture showed slight improvement, self-injurious behavior persisted but was managed with protective gloves, blood uric acid levels normalized, and renal stones decreased. Case 2, a 13-year-old boy, was hospitalized to the Nephrology Department due to urinary tract infection. Following successful control of the infection, his limb dystonia has worsened, leading to his transfer to the Neurology Ward. The patient had a history of delayed motor and language development, abnormal postures, and lip-biting self-injurious behavior, with elevated blood uric acid levels, leading to the diagnosis of LNS. His parents had declined genetic testing due to financial constraints. Following discharge, the patient did not adhere to the prescribed medication regimen or attend scheduled outpatient visits. The patient had died by the time of the 4-month follow-up contact.
CONCLUSION
Variants of the HPRT1 gene probably underlay the LNS in the two children, and the HPRT1 is the only known pathogenic gene for LNS. Early genetic diagnosis, strict adherence to multidisciplinary comprehensive treatment, and intensive intervention for self-injurious behaviors are crucial for improving the quality of life and prolonging the survival of children with LNS.

Objective:To explore the advantages of internet-based smart healthcare for full-cycle transcatheter edge-to-edge repair (TEER) management in reducing postoperative adverse events rate, improving cardiac function, and enhancing quality of life.Methods:This retrospective study enrolled patients with mitral regurgitation who underwent transcatheter TEER at Beijing Anzhen Hospital Valve Intervention Center between June 2021 and September 2023. Patients were classified into degeneration mitral regurgitation (DMR) and functional mitral regurgitation (FMR) according to etiology, with further stratification by enrollment period into usual care group (June 2021 to October 2022) and full-cycle management group (November 2022 to September 2023). The 1-year postoperative follow-up data were collected and compared between subgroups with the same etiology. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the differences in major endpoint event-free survival rates between the two groups. Univariate and multivariate Cox regression and logistic regression analyses were performed to evaluate the impact of the full-cycle management system on patients′ outcomes.Results:A total of 130 patients were included, aged (72.0±8.6) years, including 82 (63%) males. DMR was identified in 84 cases (40 in the usual care group and 44 in the full-cycle management group), while FMR was observed in 46 cases (27 in the usual care group and 19 in the full-cycle management group). Kaplan-Meier analysis demonstrated higher 1-year major endpoint event-free survival rates in the full-cycle management group compared to the usual care group, though the difference was not statistically significant (log-rank P>0.05). Compared to the usual care group, the full-cycle management group showed significantly higher proportions of New York Heart Association classification Ⅰ-Ⅱ patients (DMR: 67% vs. 52%, P=0.031; FMR: 68% vs. 52%, P=0.021), greater 6-minute walking distances (DMR: (346.39±70.41) m vs. (294.11±60.47) m, P=0.012; FMR: (356.60±54.68) m vs. (318.55±39.02) m, P=0.004), and superior Kansas City Cardiomyopathy Questionnaire scores (DMR: 81.50 (74.50, 85.00) points vs. 71.00 (66.00, 82.25) points, P=0.014; FMR: 83.00 (76.00, 85.00) points vs. 74.00 (70.75, 80.00) points, P=0.030). Multivariate logistic regression confirmed the full-cycle management system as an independent predictor for the above improved outcomes (all P<0.05). Conclusion:Smart healthcare-based full-cycle management improves cardiac function and quality of life in mitral regurgitation patients after TEER, demonstrating lower rates of major endpoint events compared to usual care.

Objective:To report the nationwide surveillance results of pathogenic profiles and antimicrobial resistance patterns of Gram-positive bloodstream infections in China in 2023.Methods:The clinical isolates of Gram-posttive bacteria from blood cultures were collected in member hospitals of National Bloodstream Infection Bacterial Resistant Investigation Collaborative System(BRICS)during January to December 2023. Antimicrobial susceptibility testing was performed using the dilution method recommended by the Clinical and Laboratory Standards Institute(CLSI). Statistical analyses were conducted using WHONET 5.6 and SPSS 25.0 software.Results:A total of 4 385 Gram-positive bacterial isolates were obtained from 60 participating center. The top five pathogens were Staphylococcus aureus( n=1 544,35.2%),coagulase-negative Staphylococci( n=1 441,32.9%), Enterococcus faecium( n=574,13.1%), Enterococcus faecalis( n=385,8.8%),and α-hemolytic Streptococci( n=187,4.3%). The prevalence of methicillin-resistant Staphylococcus aureus(MRSA)and methicillin-resistant coagulase-negative Staphylococci(MRCNS)was 26.2%(405/1 544)and 69.8%(1 006/1 441),respectively. Notably,all Staphylococci remained susceptible to glycopeptide or daptomycin. Staphylococcus aureus demonstrated excellent susceptibility(>97.0%)to cephalobiol,rifampicin,trimethoprim-sulfamethoxazole,linezolid,minocycline,tigecycline,and eravacycline. No Enterococcus exhibiting resistance to linezolid were detected. Glycopeptide resistance was uncommon but more frequent in Enterococcus faecium(resistance to vancomycin and teicoplanin:both 1.7%)compared to Enterococcus faecalis(both 0.3%). The detection rates of MRSA and MRCNS exhibited significant regional variations across the country( χ2=17.674 and 148.650,respectively,both P<0.001). No vancomycin-resistant Enterococci were detected in central China. Institutional comparison demonstrated higher prevalence of MRSA( χ2=14.111, P<0.001)and MRCNS( χ2=4.828, P=0.028)in provincial hospitals than that in municipal hospitals. Socioeconomic analysis identified elevated detection rates of both MRSA( χ2=18.986, P<0.001)and MRCNS( χ2=4.477, P=0.034)in less developed regions(per capita GDP

Objective:To report the results of bacterial resistant investigation collaborative system(BRICS)on the distribution and antimicrobial resistance profile of clinical Gram-negative bacteria isolates from bloodstream infections in China in 2023,and provide reference for clinical tretment of bloodstream infections and prevention and control of bacterial resistance.Methods:The clinical isolates of Gram-negative bacteria from blood cultures in member hospitals of BRICS were collected during January 2023 to December 2023. Antibiotic susceptibility tests were conducted by agar dilution or broth dilution methods recommended by Clinical and Laboratory Standards Institute(CLSI). WHONET 5.6 and SPSS 25.0 were used to analyze the data.Results:During the study period,11 492 strains of Gram-negative bacteria were collected from 60 hospitals,of which 10 098(87.9%)were Enterobacterales and 1 394(12.1%)were non-fermentative bacteria. The top 5 bacterial species were Escherichia coli(50.0%), Klebsiella pneumoniae(26.1%), Pseudomonas aeruginosa(5.1%), Acinetobacter baumannii complex(5.0%)and Enterobacter cloacae complex(4.1%). The ESBL-producing rates in Escherichia coli, Klebsiella pneumoniae and Proteus mirablilis were 46.8%(2 685/5 741),18.3%(549/2 999)and 44.0%(77/175),respectively. The prevalence of carbapenem-resistant Escherichia coli(CREC)and carbapenem-resistant Klebsiella pneumoniae(CRKP)were 1.3%(76/5 741)and 15.0%(450/2 999);32.9%(25/76)and 78.0%(351/450)of CREC and CRKP were sensitive to ceftazidime/avibactam combination,respectively. 94.7%(72/76)and 90.2%(406/450)of CREC and CRKP were sensitive to aztreonam/avibactam combination. Furthermore,57.9%(44/76)and 79.1%(356/450)were sensitive to imipenem/relebactam combination. The prevalence of carbapenem-resistant Acinetobacter baumannii(CRAB)complex was 64.6%(370/573),while more than 80.0% of CRAB complex was sensitive to tigecycline,eravacycline and polymyxin B. The prevalence of carbapenem-resistant Pseudomonas aeruginosa(CRPA)was 17.0%(99/581). There were differences in the composition ratio of Gram-negative bacteria in bloodstream infections and the prevalence of important Gram-negative bacteria resistance among different regions in China,with statistically significant differences in the prevalence of CREC,CRKP,CRPA and CRAB complex( χ2=10.6,28.6,10.8 and 19.3, P<0.05). The prevalence of ESBL-producing Escherichia coli, CREC,CRAB complex and CRKP were higher in provincial hospitals than those in municipal hospitals( χ2=12.5,9.8,12.7 and 57.8,all P<0.01). Conclusions:Gram-negative bacteria are the main pathogens causing bloodstream infections in China,and Escherichia coli is ranked in the top,while the trend of Klebsiella pneumoniae increases continuously with time. CRKP infection shows a slow upward trend,CREC infecton maintains a low prevalence level,and CRAB complex infection continues to exhibit a high prevalence rate. The composition and resistance patterns of pathogens causing bloodstream infections vary to some extent across different regions and levels of hospitals in China.

Objective:To investigate the neuroprotective effects of ginsenoside Rb1 in neonatal mice with Hypoxic Ischemia(HI)and analyze its potential molecular mechanisms.Methods:Seven-day-old C57BL/6 neonatal mice were randomly assigned to three groups:Sham group,hypoxic-ischemic(HI)model group,and HI model+ginsenoside Rb1 intervention group(HI+Rb1),with 10 mice per group.The modified Rice-Vannucci method was used to establish the HI model,and ginsenoside Rb1(20 mg/kg)was administered via intraperitoneal injection for 7 consecutive days post-surgery(once per day).Brain damage was assessed on days 7 and 14 post-surgery by evaluating cortical neurons and glial cell numbers,as well as the activation status of the ERK signaling pathway.Additionally,in utero electroporation(IUE)was used to overexpress the ERK signaling pathway in the cortical neurons,and the impact of ERK activation on glial cell development was observed.Further,IUE was used to overexpress ERK in the cortex of P0 neonatal mice,fol-lowed by the HI model on day 7 to analyze the effects of enhanced ERK signaling on oligodendrocyte development and myelin regeneration.Results:Compared to the HI group,the HI+Rb1 intervention group showed significant improve-ment in motor ability,reduction in brain injury area,less mature neuron loss,and increased newborn neurons.Addi-tionally,the number of oligodendrocytes in the cortex was increased,and the activation of the ERK signaling pathway was enhanced.In mice with overexpression of the ERK signaling pathway in the cortex,there was a significant increase in oligodendrocytes.In the HI model with ERK overexpression,an increased number of oligodendrocyte precursor cells were found around the brain injury area,consistent with the results of ginsenoside Rb1 intervention.Conclusion:Gin-senoside Rb1 exerts neuroprotective effects in neonatal mice with hypoxic-ischemic brain injury,potentially through the enhancement of ERK signaling,promoting oligodendrocyte proliferation and myelin regeneration.
